Plot Overview:

In Monsters, Inc. 3 (2026), the beloved monster duo, Mike Wazowski (Billy Crystal) and Sully (John Goodman), return for an all-new adventure that takes them beyond the doors of Monstropolis and into new worlds of imagination and danger. After the events of Monsters University and the transformation of Monsters, Inc. from scare tactics to laughter power, life in Monstropolis has drastically changed. But when an unexpected threat emerges that could destroy the world of monsters as they know it, Mike and Sully find themselves once again tasked with saving the day.

This time, the threat comes from a mysterious entity known as the Silent Fears, a new generation of creatures who feed off fear in a much more potent form. With the old power source of laughter becoming unstable, Mike, Sully, and the rest of the crew must embark on a high-stakes mission across the monster multiverse to unlock a secret that could save their world—or doom it to silence forever.

As they navigate unfamiliar, bizarre worlds filled with unique monsters and new challenges, Mike and Sully will have to rely on each other more than ever. Along the way, they will confront their greatest fears, uncover hidden truths about the origins of laughter, and learn what it truly means to protect the ones you love.
